MJ's modified Air Jordan 1s from 1985-86 up for auction

Three years after being sold for a then-record $55,000, another pair of Michael Jordan's game-worn and modified Air Jordan 1 sneakers from the 1985-86 season have surfaced at auction.

The latest pair was gifted to the consignor and his father from Jordan after a game, according to auction house Gotta Have Rock and Roll. The shoes were customized with straps to provide extra support for Jordan's left foot, which he fractured three games into his sophomore season, and feature mismatched sizing of 13 for the left and 13.5 for the right.

Bidding opens July 22 and starts at $100,000. The auction house estimates the shoes will fetch $300,000 to $500,000.
